SPECIFICATION forming part of Letters Patent No. 395,437, dated January1, 1889.

Application filed February 13, 1888. Serial No. 263,893. (No model.)

1'0 all whom it may concern.-

Be it known that I, SAMUEL 'l. GRIMME'JFT, residing in the vicinity of\Vest Plains, in the county of Howell and State of Missouri, haveinvented a new and useful Improvement in Car-Couplings, ot. which thefollowing is a specification.

My invention is an improvement in carcouplings employing a link and pinand seeks to provide convenient means whereby the coupling may beeffected without necessitating the operators going between the cars, andin which the links, when the cars are coupled, will play freely on thepins and the bottom of the draw-head.

The invention consists in certain features of construction and novelcomljiinations of parts, as will be described and claimed.

In the drawings, Figure 1 is a vertical, and Fig. 2 a longitudinal,section of a draw-head provided with my improvements. Fig. 3 is a detailview of a part of one of the springs. Fig. et shows a somewhat differentconstruction of sliding-pin support. Fig. 5 is adetail view of thepin-support. .Fig. 6 is a detail view of the sectional spring-retainingdevice, and Fig. 7 is a detail view of the bent link.

The draw-heads A have suitable pin-holes, u, and are provided withsliding supports B for the pin which supports are pivoted at 1), havesuitable de iiending portions, 7), for engagement by the link as thelatter enters the draw-head, and a stop or nib, (.1 is provided to limitthe 1nov(- '|nent of slide. The slide operates close to the under sideof the top wall of the draw-head and may be moved forward under thepin-opcni'ing in said top wall to secure the pin elevated until the linkin an approaching draw-lmad shall enter the first draw-head and engageand release the slide, iermitting the pin to fall through the link,completing the coupling.

The springs I) are secured in the draw-hezul and are formed with sidearms, (I, flaring at their forward ends, whereby to grasp one end of andsecure the link, whereby the opposite end of the link may be heldelevated to any desired. degree to properly enter an approachingdraw-hea( l.

The spring I) may be secured in the drawhead by bolts or by a screw, E,operating between the arms of the said spring, as shown in Fig. 1.

The screw E may be preferrelil, as its use facilitates the applicationof the spring to a draw-head and its transfer from one draw-head toanother.

The bolt or clamping device E consists of two lengths or sections, c 6,having their inner edges lapped together and movable longitudinally andtheir outer edges threaded and a nut-block, e, fitted over saidsections, so that by turning the nut in one direction or the other thesections maybe fed in or out, as desired, the nut having studs 6 adaptedto receive a wrench passed through a slot, 6, in the side wall of thedraw-head. hen the link is set and held in one draw-head, it will coupleby running the draw-heads together, and when the draw-heads are drawnapart the link drops down and plays loosely, just the same as theordinary link.

In order to supplement the springs D, it is preferred to provideauxiliary spring F, connected with the arms of springs D, to supplementthe tension of said arms. \Vhen the coupling is made and the link restedon the bottom wall of the draw-head, the ends of the link may pass underthe ends of the springs D, so the link cannot touch either of thesprings.

It will be understood that the springs D t'orm holders for the linkswhen the link held in one draw head is ready to be moved into contactwith another draw-head, so the link cannot touch either of the springs.

By preference the pin-si'ipports are carried on bars 1-3, which connectat 1-3 with the upper spring-section and extend upward and forward fromsuch connection, as shown in Fig. l.

The construction shown in Fig. imay prove desirable in large draw-heads,the said con struction comprising a support 13 sliding back and forth onthe bar B andhaving a projection, I), for engagement by the linkentering the draw-head.

Having thus deserilnsl my invention, what I claim as new is-- 1. In acar-coupling, the coinbination of the draw-head, the spring-arms securedtherein and having their free ends ar 'anged to bear close together, andone of said arms havinga socket fitted to receive the end of a link, the

pin-supporting slide, and a support therefor, substantially as setforth.

2. The combination, in a ear-coupling, of the spring-ar1ns adapted attheir free ends to hold the link, a bar secured at one end to andprojected upwardly from one of said arms, and the pin-supporting slidemounted on said bar, substantially as set forth.

3. The combination of the draw-head, the spring-arms adapted at theirfree ends to secure the link, the bar mounted on one of said arms andcarrying the pin-supporting slide, and the screw operating between thespringarms, substantially as set forth.

4. In a ear-coupling, the combination of the draw-head, the springhaving arms and secured in said draw-head and adapted at its forward endto engage and hold the link, and the auxiliary spring connected with andsupplementing said armed spring, substantially as set forth.

o. The combination of the draw-head, the spring secured therein andhaving arms adapted at their forward ends to engage and 'hold the link,and the screw operating besupporting slide movable under the upper wallthereof, the spring having arms adapted at their forward ends to engageand hold the link, the screw operating between the arms of said spring,and the auxiliary spring, substz'tntia-lly as and for the purposesspecified.

7. In a car-coupling, a spring, D, having arms bearing close together attheir free ends, and one of the arms having its free end provided with asocket to receive the link, substantially as set forth.
